These electro-thermal actuators may be used for the automatic control of the closing valves. When the actuators are mounted on the cranes, they automatically shut off the water from the boiler. As soon as there is a heat demand of the heating system, the thermostat, which is in communication with the receiver, sends a signal for the actuators to open the valves. When the correct temperature is reached, they close the closing valves again.
